BYD's blade battery can achieve a range of over 100 kilometers with a 10-minute charge?

On July 20, BYD stated in a conversation with investors that the blade battery equipped in its flagship model "Han" can be charged in 10 minutes and has a range of over 100km.

According to information previously provided by BYD, it only takes 25 minutes for Han EV to charge from 30% to 80%. Fast charging is very important for electric vehicles . Many users do not have their own charging piles and charge at public stations. At this time, users need to wait in the car or next to it. If the charging speed is slow, it will greatly affect the user experience. In addition, many users also have the need to drive long distances. If the charging speed is slow, it will greatly extend the entire journey.

Lithium iron phosphate batteries do not contain cobalt, which will cause their charging and discharging speed to be slower. Cobalt can improve the ability of lithium ions to be inserted and removed, which can increase the charging and discharging speed of the battery. However, cobalt is an expensive metal, which causes the price of ternary lithium batteries to remain high. Taking Tesla as an example, the price of the Model Y standard range version using lithium iron phosphate batteries has dropped directly to 276,000 yuan, while the other two versions using ternary lithium batteries are still priced at 340,000 and 370,000 yuan.

Power batteries are the biggest cost of electric vehicles , and major battery manufacturers are researching batteries that do not contain cobalt. Currently, this progress is relatively slow. Due to its high cost, many manufacturers are installing lithium iron phosphate batteries on more and more models, but its energy density is low, and in the same space, the total energy is not as good as that of ternary lithium batteries.

However, BYD's blade battery technology makes up for this regret. It can provide higher energy in the same volume and ensure that the vehicle has a longer endurance.

In addition to fast charging and battery life, battery safety is also a topic of concern to users. Previously, BYD showed a puncture test video of the blade battery. After being punctured, there was no safety problem, while the ternary lithium battery exploded immediately after being punctured.

However, BYD's blade battery is not foolproof in terms of safety. It still contains electrolytes, which are very likely to burn and explode when exposed to fire. Therefore, battery manufacturers are actively developing solid-state batteries, but solid-state batteries still require a long time to develop. Some industry insiders believe that solid-state batteries will be commercially available around 2025, when the safety issues of batteries will be greatly improved, and consumers can buy electric vehicles with more confidence.
